[TowerTalk] Dacron rope

Almost any stranded, non conductive rope will conduct when wet. Normally 
it's not the rope, but the crap the rope collects and the crap in 
today's rain that does the conducting.  I use end insulators where the 
Dacron connects to the ends of wire antennas. I cut Lexan rings to 
attach Dacron to my AV640. The wet guys do not affect the SWR on that 

The instructions say it doesn't need guys, but you only need watch one 
unguyed in a strong wind.  Yes, it withstood the wind, but that thing 
sure is flexible!

Right now the antenna is up temporarily, but when I drop it next week I will be installing insulators on the ends where the rope touches the driven element.
